Application filed September 23, 1908.

To all whom it may concern:

Be it known that I, ADDY S. EL-Kounr, a citizen of the United States,residing at Duke, in the county of Jackson and State of Oklahoma, haveinvented certain new and useful Improvements in Extension-Tables, ofwhich the following is a specification.

The invention relates to improvements in extension tables.

The object of the present invention is to improve the construction ofextension tables, and to provide a simple and comparatively inexpensiveextension table, designed for use in public and private dining rooms andvarious other places and equipped with means for enabling it to beinstantly adjusted to make it either larger or smaller to accommodatethe desired number of persons.

A further object of the invention is to provide an ext nsion table ofthis character, capable of djustment without taking oil the table cloth,or removing an electrolior, candelabra, or other ornamental centerpiece.

' With these and other objects in view, the invention consists in theconstruction and 11 vol combination of parts hereinafter fullydescribed, illustrated in the accompanying drawings, and pointed out inthe claims hcrc to appended, it being understood that various changes inthe form, proportion, size and minor details of construction, within thescope of the claims, may be resorted to without departing from thespirit or sacrificing any ofthe advantages of the invention.

In the drawings :Figure 1 is a perspective view of an extension table,constructed in accordance with this invention. Fig. 2 is a reverse planview of the upper portion of the Fig. 3 is a vertical sectional view onthe line 33 of Fig. 2. Fig. 4 is a detail vertical sectional view of thecentral portion of the table. Fig. 5 is a plan view of the upper portionor bed of the supporting frame, illustrating the manner of mounting themotor and the gear ing for simultaneously adjusting the movable leafsections.

Like numerals of reference designate corresponding parts in all thefigures of the drawings he table comprises in its construction asupporting frame including a central vertical hollow column 1, arectangular top portion or bed 2 and legs 3, extending from the lowerend of the hollow column.- The hollow col- Speeification of LettersPatent.

umn and the legs, which may ac constructe l of any suitable material,are preferably of an ornamental character, and the horizontal topportion or bed 2 is composed of side bars or rails, diagonal braces 3and a platform The hollow column is provided at its up er portion with aspider 5, consisting of diagonally arranged arms receiving the braces 3and secured to the lower faces thereof. The upper end of the hollowcolumn is provided with a cap 6, having a central threaded opening 7 forthe reception of the upper end of the lower section 8 of a verticaltubular conduit or member, which is also provided with an upper section9.

The lower end of the lower section is threaded and engages a threadedaperture 10 of a nut or plate 11, designed in practice to be rigidlyconnected with the lower end of the hollow column. The upper end 12 ofthe lower section of the central tubular conduit is extended above thecap 6 and screwed into the lower end 13 of the upper section 9, which is.interiorly threaded. The upper section 9 is provided at its upper end.with an enlargement or head 14-, and it forms a bearing for a rotarysleeve 15, provided at its upper end with a pinion 16 and connected atits lower end with a horizontal worm wheel 17. The worm wheel mesheswith a worm 18 of a horizontal shaft 19, journaled in suitable bearings20 and equipped with a spur gear 21, which meshes with a pinion 22 of anelectric motor 23. The platform e supports the electric motor and thebearing 20, the motor and the bearing being secured by screws, or othersuitable fastening devices to the platform. The wires 24; and 25 leadingto the motor pass upward through the central tubular conduit and enterthe same at the lower ed thereof, and they extend through registeringapertures 26 and 2. of the upper portions of the lower section of theconduit and the tubular column. The

rotor furnishes power for operating the gearing to simultaneously adjustmovable leaf sections ofthe top of the table.

The top of the table is composed of a central relatively fixed leafsection QSand four adjustable or extensible leaf sections, each composedof a wooden supporting member 29 and an overlapping relatively thinsheet metal member 30. The wooden supporting members are located at thecorners of the top of the table, and each overlapping sheet metal memberis secured to the end of the inner transverse edge of its companioncorner member, and it extends along the adjacent side of the table andoverlaps the relatively thick wooden supporting member of the contiguousleaf section. The overlapping member 30 is provided at its innertransverse edge with a substantially L-shaped attaching flange 31,secured by screws 32, or other suitable fastening devices to the woodenmember 29, and it fits against the adjacent edge and the lower face ofthe said member 29. The upper face of the relatively thin member of theleaf section is located above the upper face of the relatively thicksupporting member 29, so that all of the rela tively thin members of theleaf sections are disposed in the same horizontal plane, and have theirupper faces in flush relation, when the table is closed, as illustratedin Figs. 1 and 3 of the drawings. The outer marginal edge of therelatively thin member is equipped with a tubular guide or way 33,substantially rectangular in cross section and consisting of an outervertical wall, a horizontal bottom, and a vertical flange 34, extendingupwardly from the inner edge of the horizontal bottom wall and fittingwithin a longitudinal groove 35, formed in the lower face of therelatively thick member that is overlapped by the said relatively thinmember. The contiguous outer marginal portion of the relatively thickmember is arranged within and embraced by the hollow guide of therelatively thin member, whereby the leaf sections of the top of thetable are slidably interlocked with one another. l Yhen the table isadjusted to change the size of the top, the relatively thin member ofone leaf section slides over the relatively thick member of thecontiguous leaf section. The slidable interlocking of the adjustableleaf sections of the top maintain the said leaf sections in theirrectangular relation.

The extensible leaf sections are simultaneously moved inward and outwardand are guided in such adjustment by means of the diagonal rack bars 36,arranged in pairs, the members of each pair being disposed in parallelrelation. The rack bars, which are provided at their inner edges withteeth, mesh with the pinion 16, as clearly illustrated in Fig. 3 of thedrawings. The relatively thick wooden sections are equipped at theirinner corners with fixed inner brackets 37, preferably L-shaped in crosssection and consisting of a horizontal attachin flange and a dependingvertical flange. The depending vertical flange, which is rigidly securedat 88 to one of the members of the contiguous parallel rack bars, isprovided with a guide opening 39, receiving the other member of suchpair of rack bars. By this construction, each inner bracket is fixed toone rack bar and guides the adjacent rack bar. The inner bracket 37 isconnected by a diagonal guide rod 40 with an outer corner bracket 41,secured to the outer corner of the relatively fixed member and providedwith a depending lug to which the outer end of the guide rod 10 isattached. The guide rods 40 pass through openings 42 in the corners ofthe upper rectangular top portion or bed of the supporting frame of thetable. By this construction, the extensible leaf sections of the top ofthe table are simultaneously adjusted inward and outward.

The relatively fixed top section 28 is secured by screws 43, or othersuitable fastening devices to the upper end of the upper section 9 ofthe tubular conduit, which is provided with an interiorly threadedterminal portion 44, piercing the relatively fixed section 28 andinteriorly threaded to receive an electric light 45. The wires 46 and47, leading to the electric light, extend upward through the tubularconduit. The outer edges of the relatively fixed central leaf section 28are preferably beveled, as shown, and while the section 28 isexaggerated in thickness in the accompanying drawings, it may be madecomparatively thin, so that the table cloth will present a smoothappearance. The central section overlaps the relatively thin members oftne adjustable leaf sections, as clearly shown in Fig. 1 of thedrawings.

The table cloth 48 is designed to be provided with a central aperture topermit the base of the electric light to be introduced into the socketformed by the terminal portion 44 of the tubular conduit of thesupporting frame of the table, and the corners 49 of the table cloth aredesigned to be weighted with a small bag of shot, or other suitablemeans. By this construction, the table cloth will hang smooth and adjustitself to the table and will permit the same to be varied in sizewithout necessitating the removal of the cloth. The current to theelectric motor is designed to be controlled by a button, or othersuitable switch, and the motor will enable the table to be instantlymade larger or smaller as desired. The diagonal movement of the leafsections will cause the relatively thin members to slide on therelatively thick overlapped members.

Although i have illustrated an electric motor for operating theextensible leaves, any other suitable means may be employed forperforming this operation.

Having thus fully described my invention, what 1 claim as new and desireto secure by Letters Patent, is
